Hi and welcome on the forum,
No, sorry, it’s not possible.
Cubase LE, AI and Elements licenses are stored in the Soft-eLicenser. This means, no USB-eLicenser. Cubase Artist and Pro licenses can be stored in the Soft-eLicenser only (it’s not common flash memory, it’s a dedicated key).
Or, you can wait for the dongle-free version.
